IT must've been quite a weekend read. Hari Kunzru submitted the first draft of his book on a Friday. By Monday morning his phone was ringing. The book was sold to publishers in Britain and the US for $1.8 million. Kunzru, whose father's from Kashmir and mother English, grew up in Essex, which is to London what Haryana is to Delhi. The story of The Impressionist resembles his own: a young man of mixed parentage dealing with different worlds. He's described the book as "Midnight's Children meets Tom Jones"; his agent calls it "accessible, funny and a great story". And yes, Hollywood is interested.
